Recommendation
Avoid driving during the morning hazard window, especially before 11:00 AM EDT; if travel is unavoidable, the least-bad morning slot is 11:00 AM–1:00 PM EDT when precipitation chances drop to 43–51%, but remain alert for flooded roads. The safer evening slot is 7:00 PM–10:00 PM EDT when precipitation chances fall to 0–5% and winds are light; never drive through water-covered roads.
